Stem Cell Therapy for Ischemic Brain Injury: Early Intranasal Delivery after Cardiac Arrest.

Global ischemic brain injury is the leading cause of mortality and long-term disability in patients resuscitated from cardiac arrest. Hypothermia and neuroprotective agents are two strategies partially improve neurological outcomes following resuscitation. However, the therapeutic effects of these treatments are inconsistently reported. Stem cell therapy has emerged as a promising protective strategy due to its potential for proliferation and differentiation into functional neural cells. This editorial reviews the current status of stem cell therapy via the intranasal route in primates and clinical studies, along with the treatment window of stem cell therapy in ischemic brain injury after cardiac arrest to provide new insight into stem cell therapy for cardiac arrest-induced global cerebral ischemia injury.
